DESCRIPTION

The TS4041 is a low power shunt voltage reference providing a stable 1.225V output voltage over the industrial temperature range (-40 to +85°C). Availabe in SOT23-3 surface mount package, it can be designed in applications where space saving is a critical issue. The low operating current is a key advantage for power restricted designs. In addition, the TS4041 is very stable and can be used in a broad range of application conditions.
